refactor: replace magic bag slot offset 19 with FIRST_BAG_EQUIP_SLOT

Browse source 
- Add Inventory::FIRST_BAG_EQUIP_SLOT = 19 constant with why-comment
  explaining WoW equip slot layout (bags occupy slots 19-22)
- Replace all 19 occurrences of magic number 19 in bag slot calculations
  across inventory_handler, spell_handler, inventory, and game_handler
- Add UNIT_FIELD_FLAGS / UNIT_FLAG_PVP comment in combat_handler
- Add why-comment on network packet budget constants (prevent server
  data bursts from starving the render loop)
